WATER-HEATING ATTACHMENT FOR RANGES.

SPECIFICATION forming part of Letters Patent No. 440,970, dated November18, 1890.

Application filed July '7, 1890. Serial No. 357,976. (No model.)

To all whom it may concern/.-

Be it known that I, HENRY C. STEINHOFF, of the town of Union, in thecounty of Hudson and State of New Jersey, have invented a new andImproved \Vater-Heatin g Attachment to Ranges, of which the following isa full, clear,

and exact description.

' water-heating attachment My invention relates to ranges or stoves andmore particularly to ordinary cooking or kitchen ranges, and has for itsobject to provide such ranges with a simple, inexpensive, and efiicientsystem of water-pipes applied independently of the ordinary waterback,and adapted to heat water and maintain circulation of it throughradiators for thereby heating other rooms than that in which the rangeis set.

The invention requires little or no change in the construction and nochange in the setting of the ordinary range, and in its preferredembodiment is adapted by the simple manipulation of a damper to be madeoperative or inoperative at pleasure.

The invention will first be described, and then will be particularlypointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front vertical sectional elevation of an ordinarykitchen-range fitted with my improvement and taken on the irregular line10 w in Fig. 2. Fig. 2 is a plan view of the range and attachment inhorizontal section on the line so so in Fig. 1. Fig. 3 is a verticaltransverse sectional view taken on the line y y in Fig. 1, and asarranged for using the Fig. L is a detail View showing the guard-platesadjusted, as when the water-heating attachment is not in use. Fig. 5 isa detail front vertical sectional view taken on the line 2 in Fig. 4,and Fig. 6 is a face view of one of the heat-deflecting plates used inthe water-pipe flue.

a a lead cold water to and discharge hot water from the water-back tothe ordinary hot-water boiler. (Not necessary to show or describe, asthis boiler and water-back form no part of my improvement.)

In carrying out my invention I utilize the space usually left below thetop plate and behind the back plate of the range in which to locate thegreater portion of the auxiliary water-pipes B, which makes the heat ofthe fire-pot available for heating said pipes. In the preferredconstruction shown in the drawings the water-pipes B are arranged with areturn-bend b, which is located at the upper part of the fire-pot andforms a portion of the side wall of the pot opposite the Waterback a,which forms the opposite side wall of the pot. The lower part of thisbend b is extended outward and forms the cold-water inlet 1) to thewhole system of pipes B, and will be connected with any suitable sourceof water-supply. The upper part of the pipebend I) is fitted into ahollow coupling-box 6 made large enough to receive the ends of anydesired number of pipes 11 forming the rear horizontal portion of thewater-pipe system B. I show four of these pipes 17 but any desirednumber may be used.

A partition 0, having a rearward right-angular extension 0, is fittedbetween the top of the oven and the range-top plate and separates thespace or hot-product chamber, opening to and from the firepot a into twoindependent fiues c 0 the former overlying the range-oven and thelatterforming a rear flue traversed by the system of pipes B. The hotproducts from the fire-pot thus may be directed either through the flue0 containing the water-pipes B, or directly over or around therange-oven to the hot-product outlet or exit-flue of the range.hot-product outlet in the form of a bonnet D, which has a centralvertical partition (1 above the part c of the range-partition O, andthus divides the bonnet into two chambers d 61 both of which havecommunication with a common exit-pipe (1 which is fitted to the top ofthe bonnet and conducts the hot products to a chimneyiiue. A damper E,fitted, preferably, to the top of the bonnet-partition d, where it ispivoted, may be swung down, as shown in full lines in Fig. 1, to closethe bon- I prefer to make the net-chamber d to the exit-flue (Z and maybe swung over, as indicated by the dotted lines, to close thebonnet-chamber d to said fine. By using this double-chambered bonnet D,I am enabled to continue the series of pipes B beyond the horizontalpipes 12 by a connected series'of vertical pipes b, which range upwardthrough the bonnet-chamber (1 with which the hot-product flue ccommunicates. I prefer to connect the upper ends of these pipes b withthe hollow box-coupling 12 from which extends a pipe I), which conveysthe hot water from the entire pipe system B to any number of radiators(not shown) and placed in other apartments to heat them by the same firein the range which does the cooking for a family. I prefer to fit intothe hot-product flue c and the bonnet-chamber (1 a series ofdeflecting-plates F, slotted to admit the pipes B, and fixed to theopposite walls of the flue and chamber to retard the passage of the hotproducts and deflect them in a sinuous course toward the exit-flue toassure their best effect in heating the waterpipes.

As it is necessary to use the auxiliary water-pipe system B only in coldweather for heating adjacent rooms, as above described, it is desirableto protect these pipes from the heat of the range fire-pot at othertimes. I accomplish this by employing a guard, which may consist of oneor more refractory plates. I show two guard-plates G H, the former beingangular in cross-section and set upon the permanent fire-brick lining ofthat side of the fire-pot a, and extending over the pipe return-bend bto shield it from the heat, while the other fire-brick plate H, inconjunction with a suitable lug g, formed on the guardpl'ate. G,closesthe end of the water-pipe flue 0 to cut off therefrom the hotproducts from the fire-pot. The guard plate or shield G, and without thelug g, may alone be used, because when the damper E is set to close thebonnet-chamber d to the exit-flue cl the draft from the fire -pot willbe induced directly through the ran ge-flues c to the exit-ii no, andthe pipes 12 in the flue 0 will not be dangerously overheated. It may bepreferable, however, to use both guard-plates G H, as above described.

The operation of my invention is very simple and effective. \Vhen theguards G H. are removed from. the pipes B and their flue c and thedamperE is adjusted as shown in full lines in Fig. 1 of the drawings,the hot products fromthe fire pot Ct of the range will pass through theflue c and bonnet-chamber d traversed by the pipes 13, to heat the waterin the pipes and supply the connected radiators in adjacent rooms forwarming them; but when the damper E is adjusted as indicated in dottedlines the hot products from the range fire-pot will pass directlythrough the flue c and bonnet-chamber d to the exitflue and chimney, theguards G H being then adjusted to shield the water-pipes B from theheat.

I show the l1ot-product fine 0 with independent bottom and rear walls,connecting, respectively, with the bottom and top plates of the range;but the bottom and rear walls of said flue a may be formed by thebrickwork into which the range may be set, as will readily beunderstood.

I am aware that bodily-removable circular or rectangular fire-pots hax cbeen fitted within the main fixed fire-pot of ,a stove or range, andthat ordinary slide-dampers have also been used as guards againstneedless or excessive heating of water chambers or pipes at or next themain fire-pot when heating of water for warming adjacent rooms is notrequired, as in warm weather, but I am not aware of any priorconstruction in which a water pipe or coil has been arranged along the.side of the main fire-pot and adjacent to and back of a shoulder orledge of themain fire-pot, formed, preferably, by a brick or refractorylining thereof, whereby a simple bodily-removable shield-plate,preferably made of fire-brick, may be sustained on the fire-pot ledge toguard against excessive or unnecessary heating of the pipe or coil;neither am I aware of a prior construction in which a bodilyremovableguard or guards have been used in connection with a pipe or pipe-coil atthe side of the main fire-pot and extended into an adjacent hot-productflue, said guards serving both to shield the pipe or coil at the side ofthe fire- IOC pot and to cut off entrance of hot products to the fluetraversed by the water-heating pipes, and whereby the entire system ofauxiliary water-heatin g pipes may at pleasure be shielded fromexcessive heat from the fire -pot. Manifestly a bodily-removableimperforate guard, when taken away from pipes ora pipecoil at the sideof the main fire-pot, allows far more efficient and economical heatingof said pipe or coil than would a perforated dam-per base-plate whenthe. damper is open, as a damper and its base-plate which are not bodily removable from between the auxiliary water-heating pipes or coil andthe fire-pot would,when the damper is open,prevent full heating effectof the fire-p0t on the pipes, which is assured by my constructionallowing entire removal of the guards and consequent full exposure ofthe heating-pipes to the hot products of the fire-pot.

Having thus described my invention, what I claim. as new, and desire tosecure by Letters Patent, is
